    PR middle-end/61473
    * builtins.c (fold_builtin_memory_op): Inline memory moves
    that can be implemented with a single load followed by a
    single store.
    (c_strlen): Only warn when only_value is not 2.

    * gcc.dg/memmove-4.c: New testcase.
    * gcc.dg/strlenopt-8.c: XFAIL.
    * gfortran.dg/coarray_lib_realloc_1.f90: Adjust.
